From Smartflys website: "The TurbrReg has dual regulation transistors with a common control circuit. The dual transistors share the current through the regulator resulting in a more reliable regulator."

So it is not a single reg.. it has dual reg transistors.. I am guessing because they are the more likely part to fail. They are controlled by the same circuitry, hopefully this part is not as prone to failure as the transistors.. I would think Smartfly built this item from the ground up to be as reliable as possible, since it is aimed at 35-40% planes and Smartfly has an excellent reputation for electronics.
